Lemon Verbena

Also known as: Lemon verbena, Lemon beebrush, *Lippia citriodora*, *Aloysia citriodora*

Overview

Lemon verbena (*Aloysia citriodora*), native to South America, North Africa, and Southern Europe, is an herb known for its leaves rich in polyphenolic compounds. This plant is traditionally utilized to address digestive issues, insomnia, and rheumatism. Its modern applications pivot towards its antioxidant and anti-inflammatory properties, with significant active compounds including verbascoside, neral, and geranial. Despite encouraging evidence from preliminary in vitro and animal studies, human research is limited, indicating a necessity for further investigation to substantiate its efficacy and safety for widespread use.

Benefits

Lemon verbena is primarily noted for its antioxidant and anti-inflammatory effects, which may help reduce muscle damage and soreness post-exercise. Additionally, it shows potential anxiolytic, neuroprotective, antimicrobial, and sedative effects as evidenced in cell cultures and animal models. Athletes, in particular, may achieve benefits from reduced muscle damage after rigorous exercise. However, data regarding the strength of these effects in humans is scarce, emphasizing the need for additional studies to ascertain clinical significance and dose-response relationships.

How it works

The biological mechanism of lemon verbena involves the activation of antioxidant pathways, particularly via enhancement of glutathione peroxidase activity, which assists in mitigating oxidative stress. Its anti-inflammatory properties suggest interactions with both immune and nervous systems, potentially influencing pathways associated with stress response. Specifically, polyphenols, including verbascoside, are anticipated to act on oxidative stress pathways, although detailed insights into human bioavailability remain partly obscure.

Side effects

While lemon verbena is generally regarded as safe, comprehensive safety evaluations in humans are lacking. Common and uncommon side effects are not well-documented, owing to limited human studies. Rare side effects remain unknown. Potential risk factors include interactions with medications that impact the nervous system or immune responses. Furthermore, no explicit contraindications exist, but caution is advised during pregnancy and breastfeeding. It is recommended that individuals with severe health conditions or children consult health professionals before use due to the uncertainty regarding safety and efficacy.

Dosage

The minimum effective dose of lemon verbena remains undetermined, though a study indicated an optimal dosage of 400 mg/day of extract. There is no established maximum safe dose, underlining the need for individualized consultation. Generally taken daily, benefits may become apparent after several days of consistent supplementation. Capsules are a common delivery method, yet absorption factors are not clearly understood. As such, further research is warranted to pinpoint precise dosage requirements and upper limits.

FAQs
